FRANK WAGNER, OF NEW YORK, 1v. Y.

FLOOR-PLAN ING MACHINE.

Application filed May 13, 1912.

To all whom it may concern:

Be it known that I, FRANK l/VAGNER, a citizen of the United States, residing at 331 East Twenty-sixth street, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Floor-Planing Machines, of which the following is a specification.

My present invention relates to floor planing machines and embodies many novel features and advantages that will be apparent to those skilled in the art, among which may be specified means for accurately determining the depth of the cut by the machine and improved means for taking up the cuttmgs.

The drawings show only one form of embodiment of my invention and in them Figure 1 is a side elevation of a floor planing machine within my invention; Fig. 2 is a plan of the lower part of the machine shown in Fig. 3; Fig. 3 is a vertical section on the line 33 in Fig. 2 looking in the direction of the arrows; Fig. 4 is a vertical section on the line 4c1 in Fig. 2 looking in the direction of the arrows; Fig. 5 is a vertical section on the line 5--5 in Fig. 1 looking in the direction of the arrows; Fig. 6 is a horizontal section on the line 6-G in Fig. 5; and Fig. 7 is a perspective of the sand-paper roller.

The machine does its work while being pushed over the floor by the handle 1, whose legs 1 are pivotally connected with the axle 2 (Fig. 2) extending through bearings in the side of the body 3 of the machine, said axle having wheels 4 on which the rear of the machine has rolling support. The lower end of these legs of the handle, have vertical slots 5 (Figs. 1 and 2). Bolt-screws project through the slots into the machine body 3. The foregoing permits the handle to be adjusted to suit the height of the user.

7 is a revolving cutter (Figs. 1 and 2) having a plurality of spiral "knife blades, said cutter being journaled in the side of the machine body 3 at its front. It is driven in the direction of the arrow in Fig. 1 by a belt 8 from the driving pulley of an electric motor 9 bolted 0n the top of the machine body 3.

10 is a switch and 11 is a rheostat carried by the legs 1 of the handle, both being suitably wired to a current source of supply and to the aforesaid motor to control its operation.

12 (Fig. 1) is a suction fan carried by the machine body under the motor for delivering the cuttings from the rear of the revolving cutter up the pipe l-t to a bag or recep tacle 15, whose top only is shown for convenience in Fig. 1. This suction fan 12 comprises a shaft 16 journaled in the side of the machine frame having supporting blades 17 (Fig. 4:).

18 is a pulley on the fan shaft driven by a belt 19 from the motor 9 so as to revolve in the direction indicated in Fig. 3 to create a strong blast of air up the pipe 141 to the dust and shavings receptacle 15. The cylindrical casing 20 of the suction fan is closed except at the top where it connects with said pipes 14 (Fig. 3), and exceptat its ends (Fig. 4;) where-it has enlarged openings 21 concentric with the fan shaft 16.

22 (Figs. 3 and 4) is the mouthpiece of the suction fan connected by pipes 23 at the sides of the cylindrical casing 20 with the openings 21 in the ends of said casing. The result is that the revolving blades, 20 create a suction into the mouth-piece 22, which carries the dust, cuttings and scrapings created by the cutter from the rear thereof up the pipes 23, and thence by way of the openings 21 up the pipe 1 1 to the receptacle 15.

The foregoing construction is adapted to give an unusually powerful suction with minimum interference by the cuttings with the revolving blades 17.

In operation, the machine rests at the back upon the wheels 1 and in front upon the revolving cutter 7 which is caused to cut into the floor by the weight of the machine frame 3 and of the superimposed motor 9. However, I prevent the cutter from cutting too deeply into the floor, and in fact I control the depth of the cut by vertical adjustable trucks 4:0, as follows: 26-26 are vertical guides on the sides of the machine frame at the ends of the cutter. 27-27 are slides in these guides; compare Figs. 5 and 6 with the other figures. 2828 are horizontal arms centrally pivoted at 29 on the lower end of each slide 27. 30-30 are rollers mounted between the ends of each pair of arms 28. 3131 are lugs projecting from the frame 3 over the upper ends of the slides 27, each lug has a vertical hole tapped through it to receive an adjustment screw 32, whose free end has a reduced cylindrical portion 32 (Fig. 5) projecting through the lug 33 that forms the top of the slides 27.

Below said lug each adjustment screw has a washer 34 and a cotter pin 35. The result of this construction is that the weight of the forward end of the machine rests on the revolving cutter which continues to cut deeper and deeper until automatically stopped by the shoulders 36 (Fig. 5) on the adjustment screws 32 sinking into contact with the top of the slides 27, whereupon the cutting ceases because the cutter is then upheld just off the floor by the described trucks 40. It will now be apparent that the distance by which the shoulders 36 are separated from the tops of the slides 27 determines the depth of the cut, so that this depth can be determined beforehand and fixed at any desired depth by adjusting the screws 32. Thus if the desired depth of cut be onesixteenth of an inch, then the screws 32 are preliminarily adjusted so that when the cutter is resting operatively on the floor there is one-sixteenth of an inch between each shoulder 36 and the top of its slide 27. The ad vantage of this automatic certainty in the depth of the cut will be appreciated. Each adjustment screw 32 has a lock-nut 60 to maintain it in the desired adjustment.

When all of the floor has been gone over with the revolving cutter, then I finish the operation by replacing the cutter with a sand-paper roller 50 (Fig. 7) of any well known or preferred construction. For this purpose the front parts 51 (Figs. 1 and 2) of the bearings for the revolving cutter are made readily removable.

What I claim is:

In a floor planing machine, a frame, a cutter operatively supported on said frame, said frame being provided with projecting lugs having over-hanging upper ends and under cut guide grooves formed in the lower part, slides mounted movably in said guide grooves, the lower ends of said slides being spaced from the frame, arms pivoted centrally to the lower end of each slide, journal pins connecting the respective ends of said arms, rollers carried by said journal pins and adapted to roll on a supporting surface, and means engaging the over hanging portions of each lug and having loose connection with the respective slide to permit movement thereof and limit the extent of said movement.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK WAGNER.
